Let me start by saying the wiring in my apartment is a joke. The house is 100+ years old and very charming, but there's no grounding (there are grounded outlets, but the grounding screws are attached to nothing). If we turn on the steam iron and the hair dryer at the same time, we trip the breaker. So of course, amplified instruments are prone to buzzing like a swarm of angry hornets.

I have a SR5 HP, and it's always amazed me that this bass exhibits absolutely no buzzing problems, either in my home or on any stage I regularly play on. I wouldn't expect the piezo to buzz (it doesn't), but when I turn the blend to 100% magnetic pup, I still have no problems at all with 60-cycle hum. It's dead quiet in the full forward and full backward toggle positions, and the middle position has just a bit of buzz.

I recently purchased a Sterling HH, and with this bass I am hearing a lot of 60-cycle buzz. Toggle position has no effect on the amount of hum, and touching the strings or bridge makes no difference at all. It's not as bad as my Warwick with passive J-style pups, but it's pretty annoying. I can mitigate it by shifting positions on the couch, as it seems to be sensitive to what direction the bass is facing.

I bought the Sterling used from a highly-rated TB member, who told me that it had just come back from EB where they replaced the neck pup. This is clearly the case, as the neck pup is visibly cleaner than the bridge pup. The seller said that EB gave the bass a complete once-over and declared everything in as-new condition (it is a totally clean bass... you have to look really hard to see any signs that it's ever been played).

So my question is... is the buzz problem inherent in the HH configuration? If so, what's the magic mojo in the Stingray HP configuration that makes it so deadly quiet? I assumed that "humbucker" means "humbucker" no matter whether you have one or two of them on the bass. But the Sterling is clearly not bucking the hum as efficiently as the Stingray.

What gives?

I'm guessing that's a wiring problem. I had an SR4HS that buzzed in positions 2 + 4 and I found the S was wired to the switch backwards.

Along the lines of the forum and BP, I'd recommend you contact EBMM support about the problem. An HH should be very quiet.

Best of luck,

Bob

Do you get a drop in hum when you touch the control knobs or the jackplate? If so, then the ground wire to the bridge is not working correctly and needs to be checked at both ends.

I suggest to try that Sterling HH in some other places (rooms, halls...) and if it's the same, than contact customer service!

Maybe is problem in Your room! (electric installations, high electro magnetic field, thyristor controlled light...etc.) ;)

Nope, no difference at all whether I'm touching metal parts on the bass or not.

You're probably right, I should wait until I've gigged it a few times before panicking! As I mentioned in the OP, the wiring in my apartment is a disaster. I also have flourescent "green" bulbs in all of my light fixtures, which certainly doesn't help.

I was mainly curious about the significant differnce betweent the single H Stingray (which makes no noise at all) and the HH Sterling. I was wondering if there's something fundamentally different in the way the two basses are wired that could account for this difference.

Well, actually it could be just one thing which comes to my mind, ...Sterling's ceramic Humbackers have stronger magnetic field instead Stingray's alnico.
Sterling's are also wired in series, what means in theory double electric impedance/stronger output signal!
So, Sterling's pickups are more sensitive on some electromagnetic influence, what means they can pick up stronger useful and useless signals!
(That's my personal opinion but someone from EBMM can confirm right/wrong)

But, could be anything, ...make some gigs first and than decide what's next!

Now that is an interesting thought! Anyone from EBMM have any thoughts on this? Could a possible side effect of a Sterling's "more aggressive" series wiring be a greater sensitivity to electromagnetic intereference?

Nope. I had both dual pup SRs and Sterlings and both were very quiet (humbuckers buck hum after all). This is a job for EBMM CS

I tried it in other rooms in my house (including the GFS outlet in the kitchen) and no difference. So I stopped by the house of a friend this afternoon... his house is new and his electrical is all up to snuff. No difference.

So, I've sent a message to EBMM customer service. Man, I hope this is something I can get straightened out locally... my band has a charity gig and a showcase coming up, and I sold my only other fretted bass to buy this Sterling!

:(

OK , You did the right thing, it seems that definitely something's wrong with this bass!

Anyway, in theory Humbacker is very quiet (series or parallel) and it's impossible to reproduce any hum, but in special circumstances it is possible to pick up some electromagnetic interference, but that happen very rare and in very weird places!

Are you sure it is the bass? It is quite possible that there is another weak link in the chain, such as a bad cable, bad amp, bad....well anything. Can you take the bass down to a music store to "try out a bass amp you are interested in buying" and plug into their rig? If their rig is quiet (and so it should be) when you plug your bass in, likely it isn't your bass that is the problem.

The reason I'm thinking that's not likely is that my Stingray, using the same cables into the same amp with the same settings in the same room, makes no noise whatsoever. Unplug the 'Ray, plug in the Sterling, and there's the buzz.

BassMent, are you in NY? Perhaps I can loan you a bass for the charity gig...

Man, that is such a nice offer! Thank you for your generosity! I'm in Providence, RI (about 4 hours to NYC).

I was experimenting with my Electro-Harmonix Hum Debugger last night, and it cuts about 80% of the noise. It sucks a bit of tone too, but not so much that I'm going to lose sleep over it. That will work as a band-aid until I can send her on another round trip to San Luis Obispo (which is what EBMM customer service is recommending).

Thanks again!

:D
